High-brightness Dudnikov – type H - ion source at INR RAS Development of the high-intensity H- ion sources with peak current ~ 100 mA and small emittance by V. G. Dudnikov made significant influence on design of INR RAS linear accelerator and experimental facility. Dudnikov – type H- ion source (Penning discharge) had been built at Novosibirsk and delivered to INR RAS in beginning of 80 th. The ion source produced 100 mA H- ion beam with small emittance and with rep. rate 50Hz. Viktor Klenov started to work with the H- ion source at INR RAS. He was V. G. Dudnikov student at Novosibirsk and contributed to development of the H- ion source with high-brightness ion beam. The INR RAS linear accelerator has H- ion beam injector equipped with Dudnikov – type H-ion source. Viktor Klenov (left) and Alexander Belov (right) at H- ion injector at INR RAS
